Hi all, is there anyone who as the schematic of this voltmeter?
Where i live (Italy) ther's no way to buy item explained on the Oxy hacker..,
but  we can have similar voltmeter based upon 7106 IC.
The question is about how to locate the resistor to cut since R3 or oters #
are not printed over the unit, so I need to know at wich component, pin etc..
is this resistor conected.

Thanks

Roberto
